Adding State Policy aware UI controls

Adding State Policy aware UI controls

Use the IPolicyTargetLayoutComposite's add methods to add State Policies aware UI controls. These methods take a PolicyActionContainer object as their final parameter. This ensures that a StateChangeTarget is added to the PolicyActionContainer for each UI control that is added to the composite

If you are Creating a State Policy aware dialog, use the IPolicyTargetLayoutComposite in the createDialogContent method. Otherwise, use the PolicyTargetCompositeFactory to get an IPolicyTargetLayoutComposite instance.
